scratchbox run_me_first.sh doesn't exist
 

hi
i have installed Scratchbox by the GUI installer
The installation stops on the step of installing Maemo SDK and it says I have no user. As I try to add the user by /scratchbox/sbin/sbox_adduser it tells me that "run_me_first.sh has not been run". That file doesn't exist.
I tried to add the repositories from here: http://wiki.maemo.org/Scratchbox_repositories
but it tells me that .../binary-amd64 does not exist
I use Ubuntu 64-bit
what should I do?
